Crystals Procurement Notes

Verify the complete part number including suffixes against official manufacturer documentation to ensure correct load capacitance and tolerance specifications. Confirm package dimensions and pin configuration match the target PCB layout. Request updated datasheets directly from CTS-Frequency Controls or authorized distributors to validate current manufacturing status and compliance certifications prior to procurement.

Crystals Selection Notes

Select this component when a 25 MHz reference with tight ±10 ppm stability is required in a small surface-mount form factor. Ensure the application circuit can accommodate the 10 pF load capacitance and 100 Ohm ESR characteristics. Verify that the operating temperature range of -40°C to +85°C meets the environmental requirements of the final device.

Crystals Part Context

This crystal belongs to the 402 Series from CTS-Frequency Controls, which offers various SMD crystal options. The 402F2501XIAT specifically addresses the need for compact, high-stability timing components in modern electronics where board space is limited but precision is critical.

Crystals Replacement Considerations

Cross-reference with other 25 MHz SMD crystals from CTS such as 402F2501XIJR or 402F2501XIAR if different load capacitances are needed. Ensure any substitute matches the 100 Ohm ESR and HC-49/US-SM package dimensions for direct compatibility.
